▪︎HERE IS YOUR ANSWER⤵️

In circle, Point P is the centre of the circle.

segAB, segCD & segXY are the chords of the circle.

PD=12cm, AP=9cm, AB=13cm

So, PB=4cm

PX=PY

Let, PX = PY = x

By internal division of chords AB & XY,

PA × PB = PX × PY

9 × 4 = x × x

36 = x²

By taking square roots,

x = 6cm

Hence, PX = PY = 6cm.

Now,

XY = PX + PY

XY = 6 + 6 = 12cm.

Therefore, Length of Chord XY is 12cm.
